OK18 wont get scanias, too big around woodhouse estate & they ground out leaving tottenham estate coundon.
I suggest the citaros are being "sourced" from either Oxford city bus or Southern Vectis, I dont think enough time has passed for them to be new build.
Ex metrolink scanias I think will be joined by the ok scanias on the lime 8/78 split between chester & stanley with the B10s seeing off the spds.
The X21 has 7 registered routes from chester le street to gateshead, so yoy may see one passing wrekenton or heworth depending which routes are handling the traffic better.
